received: 23/sep/2008, accepted: 23/nov/2008oct-4/ pou5f1/ oct-3, a pou domain family protein acts as a crucial transcription factor dur- ing embryonic development. it helps in maintenance of self renewal as well as pluripotential state of embryonic stem (es) cells. its expression starts right from 2 cell stage especially prior to 8 cell stage till the blastocyst stage where it is strongly exp...

Stem cells are undifferentiated that can proliferate, regenerate, develop into differentiated cells, and produce a variety of tissues. Embryonic stem adult or somatic pluripotent the three types cells. Another classification is totipotent, multipotent, unipotent cell treatment has possibility treating degenerative disorders, cancer, restoration damaged tissues, all which now have no restricted ...

Cardiovascular disease remains the leading cause of morbidity and mortality in the United States and Europe. In recent years, the understanding that regenerative processes exist at the level of the myocardium, has placed stem cell research at center stage in cardiology. A stem cell is a cell that has the ability to divide (self replicate) for indefinite periods often throughout the life of the ...

Bone tissue engineering has been one of the most promising areas of research, providing a potential clinical application to cure bone defects. Recently, various stem cells, including embryonic stem cells (ESCs), bone marrow-derived mesenchymal stem cells (BM-MSCs), umbilical cord blood-derived mesenchymal stem cells (UCB-MSCs), adipose tissue-derived stem cells (ADSCs), muscle-derived stem cell...

introduction: the aim of this study was evaluate the ability of notochord to induce neural induction and/or differentiation of mouse embryonic stem cell to neuron and motor neuron, respectively. methods: in order to produce embryoid bodies, es cells line royan b1 were grown in suspension in the absence of lif for 4 days. ebs were divided into 4 groups. ebs in group 1 & 2 were further cultured i...

regenerative capacity of mammals is limited and can rarely regenerate a specific organ or tissue fully. due to these limitations, regenerative medicine seeks efficient and safe cell sources for regeneration of damaged tissues and organs or treatment for incurable diseases. human embryonic stem cells (hescs) hold two important properties called self renewal and pluripotency. however, the use of ...

The possibility to reprogram somatic human cells will greatly and deeply change genetic approach and allow the development of new tools to study genetics diseases. Indeed, our ability to study human genetic diseases suffers from the lack of valid in vitro models. The latter should (i) be originating from human primary cells, (ii) be able to self-renew for a long time and (iii) be able to differ...

the stem cells can be considered as the miracle of creation, because, they are a major reservoir of the bioactive factors, molecules and cells. these reservoir cells play a major role in development and growth of the tissues and organs. regardless of the differences in differentiation capacity of embryonic and adult stem cells, both the cells are rich sources of stem cells with therapeutic appl...
